SPECIFICATION forming part of Letters Patent No. 433,097, dated July 29, 1890.

Application filed January 23, 1889- Serial No. 297,298- (No model.)

To all whom, it may concern.

Be it known that I, JACOBS \V. SCHUCKERS, of Newark, in the county of Essex and State of New Jersey, have invented an Improvement in Type-\Vriting Machines, of which the following is a specification.

This invention relates to that class of typewriters in which there are keys to be depressed successively by the action of a finger, and these keys move frames to turn the type-Wheel a greater or less distance to bring the proper type in line for impression upon the paper, and by a continuation of the move ment of the key the type is impressed upon the paper and the feed takes place between one impressiop and the next.

In the drawings, Figure l is an elevation with the ranges-of keys and the frames carrying the same removed. Fig. 2 is a sectional plan View at or near the line 00 as, Fig. 4, Fig. 3 is a vertical section through the type-wheel and paper-roll,the other parts being in section near the line y 1 Fig. 1. Fig. at is a section through the frame carrying the keys at the line ,2 2, Fig. 3. Fig, 5 is an elevation of the type wheel with a portion of the rear plate removed, and Fig. 6 is a rear view of the inking-pad and a portion of the frame for the paper-holding roll, showing also the spacing mechanism. Fig. -7 is a detached view of one key. Fig. 8 is a plan of the rack for moving the type-wheel, and Fig. 9 shows the ends of the detent and latch in plan and elevation.

The paper-carrying roll A is mounted in a frame B, to which a longitudinal movement is given for spacing the letters and the words as the writing progresses, and the guides for holding the paper around the roll A may be of any desired character such as is usual in typewriting machines.

The frame B is supported in a stationary guide-bar C, in which stationary guide-bar the frame is free to be moved endwise, and there is a rod O attached at one end to the frame B and sliding through a guide 4 upon the bar 0, and around this rod 0 is an ex pansive spring 3, that tends to move the frame B and paper 7 carrying roll endwise whenever the latch D is lifted from the rackteeth 5 upon the frame B. This latch D is acted upon by the mechanism hereinafter described, and each tooth 5 is of such size that the proper space will be allowed each movement for impressing the type, and the space between one word and another is made by lifting the latch D without impressing the type, a space-keybeing provided for that purpose.

The type-wheel E is upon an axis (5 in the frame 0 and this frame C and the stationary guide bar 0 are connected to the bedpiece 0 and there are side plates 0, that rest upon the table or support and are connected at their back ends to the bed-piece C and there are tie-rods 0 connecting these plates 0 firmly together. There are holes through these side plates 0, in which the rods F F and G G slide freely, and it is preferable to introduce'rollers 8 beneath the rods G G to lessen the friction and cause said rods to move endwise more easily. The rods F F are connected together by the cross wires or rods 10, and the rods G G are connected together by the cross wires or rods 11, so that these respective rods and cross-wires form two laterally-sliding frames, one of which serves to control the, feed of the paper and to give the impression of the types and the other to turn the typewheel to the proper position, as more fully described hereinafter.

Above the side plates C and resting upon the ledges 12 are end frames H, connected by tie-rods 13 and these end frames are grooved vertically upon their inner faces to receive the ranges of frames I, carrying the banks of keys. Each of these frames I is made of pairs v of bars fastened together and to the end verbetween the top and bottom pairs of longi tically with freedom, and at the upper end of each key is a finger-piece 16, having upon it the letter or character corresponding to the letter or character upon the type-wheel that will be impressed by the action of such key, and there is a spring 17 to each key to elevate the same, and this spring is preferably within a vertical slot in the plate forming the body of the key and around a vcentral wire or bar within such slot, the bottom of the spring resting upon the top edges of the bottom pair of bars in the frame I, and the top of such spring bearing against the metal of the keyplate at the top of the slot. One of these keys is shown separately in Fig. 7, and each key has a cam-slot 2Q, that serves to bring the type-wheel to the'proper position for the letter corresponding to the key to be impressed, as hereinafter-described, and an incline 21 on one edge that serves to feed the paper along the proper distance and to give the impression of the type against the paper. It is, however, to be understood that the spacekey shown at K, Fig. 4, will not have any slot in it to move the type-wheel, but only the incline 21 to feed the paper, and as the typewheel is restored after each moveme'nt to a position where there is not any type to be impressed, there will not be any character or letter printed when the space-key K is pressed down. y

Upon reference toFig. 4 it will be observed that each cam-slot 20 at its lower'end is directly above one of the cross-wires 11 of the frame G, and these cam-slots are inclined more or less either to the right or left, as illustrated in Fig. 4, and the upper ends of these cam-slots 20 are vertical. The result of this is that the frame G is moved a grcateror less distance either to the right or to the left by the depression of any one key K,and that movement is sufficient to partially rotate the type-wheel to the desired point, and this is effected by means of the frame L, that rises above the bars G and carries upon its upper surface a rack with teeth 23, that gear into the pinion; upon the arbor 6, of the typewheel, so that as the frame of bars G, crosswires 11, frame L, and rack 23 are moved by one of the cam-slots 20 the type-wheelEwill be turned the required distance to bring the proper letter into line to be impressed.

In type-writing machines it is usual to have .two sets of type, one large and the other small.

. ,,well known, the types of one size occupying half of the circle and the other size occupythe slot that is provided for.it in the top bar G and passing through a mortise in the rack of the frame L, and with this object in view I employ a lever 26, pivoted-at 27 on the bar bar 23, and at the upper end of this lever 26 is a handle and a pin 28, and at one side of the frame L is an upward-projecting frame,

L, withtwo holes in it, so that when the pin Type-wheels of this character are 28 is inone of the holes, as shown in Fig. 1,

the rack-bar will occupy such a position that one set of type willrbe employed, and if the lever 26 is moved so as to carry the rack 23 endwise and rotate the pinion 24 and type- Wheel until the pin 28 passes into the holes 30 in L the type-Wheel will have made a half revolution and the second set of type be brought accurately into position for use. It

is to be understood that the top bar of theframe L is slotted where the lever 26 passes through the same sufficiently to allow for the movement of the lever 26 from one position to the other.

The type-wheel that I prefer to use is made with a series of mortises parallel with the axis and arranged in a circle, as indicated in Fig. 5, each type being in a radial plane and guided at the outer and inner edges in V- grooves provided in said type-wheel, and the pivoted at 32 and having a slightly tapering end 33, which is immediately behind the type that is vertically above the axis of the type-V wheel, so that when this impression-lever is actuated the end 33 will press the type forward against the action of its spring 0 and-' 5 give the impression upon the paper as such paper rests against the carrying-roll A. There is upon the backof the type-wheel E a ring 35 with segmental openings or slots to allow the end 33 of the impression-lever to pass IOD through and act upon the type that may be in line with it; but this ring laps upon the V- shaped edges of the types at their bases 'suf-' fi'ciently to prevent them being pushed too far backwardly by the action of the spring :05

O. The impression-lever Nis thrown back by a spring 36, and the movement is arrested by a stop 37, so that such impression-lever has but a slight movement, and by reference to Figs. 1, 2, and. 3 it will be seen that upon the no rear rod F there is a finger 38 with an inclined end that comes into contact with the incline upon the lower end of the impressionlever N, and these parts come into contact after the type-Wheel has been setin its proper I 15 position and during the end movement given to such rod F and the cross-bars 10 by the keys, as next described, so as to print the letter. The inclined edges 21 of the keys K come into contact with the cross-bars 10 and move them to carry the rods F endwise and feed the paper, as hereinafter described, and after doing so the inclined end of the finger 38 presses upon the lever N to print the letter or character, as before described. One of I2 5 the cross-wires 10 is projected to the rear, as seen in Fig. 2, and the end passes into the slot upon the lower end of the cam-lever P, and the upper end of this cam-lever P acts upon a pin 40, that projects from the lever 41, I 3'0.

the fulcrum of which is at 42, and there is a stud 43, Fig. 6, upon the latch D, which stud rests upon this lever 41, so that when the frame composed of the rodsF and cross-wires 10 is moved by the contact of the inclined edge 21 of either key with one of such crosswires 10 the cam-lever P is moved and the latch D raised to allow the spring 3 to move the frame B and roller A endwise one tooth upon the rack 5, and upon reference to Fig. 6 it will be seen that this latch D has two ends to it, so as to act like a watch-escapement and allow only one tooth at a time to pass by, and the spring 41 holds the latch in its normal positiornand this feed takes place before the end of the finger 38 comes into contact with the impression-lever, and the upper end of the cam-lever P, being nearly an arc of a circle, the latch D is not lifted beyond the required amount and remains stationary during the impression of the type.

Upon reference to Fig. 4 it will be observed that the inclines 21 on any one key com mences to act against one of the cross-bars 1O slightly before the lower end of the camslot 20 reaches one of the cross-bars 11; hence the frames composed of the rods F and crossbarslO and the rods G and cross-bars 11 are respectively moving at the same time, or nearly so, the one to bring into action the paperfeed and the other to turn the typewheel around to the proper position, and the paperfeed ceases to act when the cam at the upper end of the leverPhas raised the leverl, and the movement of the type-wheel ceases when the vertical part of the cam-slot 20 isin contact with the cross-wire 11; hence during the further downward movement of the key the inclined edge 21, in moving the wires 10 and rods F, simply impresses the type by the action of the finger 38, as aforesaid. As the key which has been impressed rises, the spring 50, Fig. 1, draws the bars F and their crosswires back to the normal position until the collar 51 stops against one of the end frames and the cross-wires 11 and rods Gare restored to their normal position in consequence of the lower ends of the cam-slots 20 being vertically in line with such wires 11; but in order to prevent the wires 11 and rods Greceiving an end movement accidentally, and thereby not remaining in the proper position for the-keys,

I make use of the detent Q, that drops into the notch in the back rod G. This detent is pivoted at 52 and is pressed down by a light spring 53, and at one side of the detent Q a pin projects, and there is a latch R pivoted at 54 on the back rod F, and the end of this latch is inclined at 61 to rununder the pin 60 on the detent Q and lift the same, and the parts are to be so timed that incline 21 on either key gives motion to the rod F before the rods G and Wires 11 are acted upon suliiciently for the latch Rto lift up this detent Q and liberate the rods G and the cross-wires thereof, and this latch B being pivoted at 54, its incline 61 will pass freely above the pin on the detent Q during the return movement of the parts to their normal positions.

The types upon the type-wheel are to be inked in any ordinary manner. Usually it is only necessary to employ pads S upon the plate S, that extend above the frame 0 such pads being at each side of the type that is projected when the impression is made, and, these pads S being of felt or similar material and with their surfaces in line with the faces of the type, the ink is spread upon such types 'as the type-wheel is partially revolved, care being taken to prevent the pads causing friction upon the types to interfere with the movement of the type-wheel.

I do not limit myself to the particular typewheel represented, as the keys, rods, cross,

keys K, the frames I for supporting the keys,

the end frames lI, connected together and receiving the frames 1, the side plates G with ledges'upon which the end frames rest removably, and the rods and cross-wires upon which the keys act in giving motion to the type-wheel and paper-carrying mechanism, substantially as set forth.

The combination, with a type-wheel, of the impression-lever with one end adapted to press upon the type that may be in posi vtion, the ranges of keys, a frame formed of the rods F F and cross-wires 10, acted upon by such keys, and the finger 38 011 one of the rods F,'for acting upon the impression-lever, substantially as set forth.

at. The combination, with ranges of keys, of the rods F, cross-wires 10, acted upon by such keys, the cam-lever P, receiving its motion from the rods F and wires 10, the lever 41, and latch D therewith connected, the rack 5, frame B, and paper-carrying mechanism, substantially as set forth.

5. The combination, with a type-wheel having two sets of characters around its periphery, and a pinion and rack for moving the same, of the frame L, receiving the rack, and

mechanism, substantially as specified, for sliding the rack and frame and revolving the type-wheel to bring the proper letter into po sition, and mechanism for moving the rack ITO endwise in the frame to throw out of action one set of characters in the type-Wheel and bring into position another set of characters, and means for holding the rack in position when adjusted, substantially as specified.

6. The combination, with the frames composed of the rods F and G and cross-wires 10 and 11, of the detent Q, the end of which passes into a notch in one of the rods G, a

T0 latch R,- pivoted to the rod F, for lifting such detent, and the ranges of keys acting upon the cross-Wires 10 and 11, respectively, substantially as set forth.
